At very high pitches, the delay-line length used in the string may
become too short for the implementation used, especially when using
vectorized module signals (sometimes called ``chunks'' in place of
samples [358]). In this case, good results can be obtained by
replacing the filtered-delay-loop string model by a simpler model
consisting only of a few parallel, second-order filter sections or
envelopedsinusoidal oscillators, etc. In other words, modal
synthesis (§8.5) is a good choice for very high key
numbers.
